UNS-1Ew | SBAS-Flight Management System

Brochure

The UNS-1Ew features a self-contained design which includes control/display functions and the Navigation Computer Unit (NCU) with integral GPS/SBAS receiver. The system includes a graphics- and video-capable 5-inch diagonal display with a housing depth of approximately 9 inches.

A special package version, the UNS-1Espw has a reduced depth and includes the same features with the exception that it is an all-digital system only. The UNS-1Espw is ideal for applications where console or panel depth pose an integration challenge. Analog Roll steering and discretes are included with the UNS-1Espw.

Avionics for you, your aircraft and the way you fly - Universal Avionics.

Platform for NextGen and SESAR

The avionics systems you invest in today must be able to support the Next Generation
of Communication, Navigation, Surveillance / Air Traffic Management (CNS/ATM).
They must possess the processing power, speed, memory and interface capabilities
to meet the growing demands of the US Next Generation Air Transportation System
(NextGen) and Europe’s Single European Sky ATM Research (SESAR).

Since introducing the industry’s first multi-sensor FMS (the UNS-1) in 1982, Universal
Avionics has continually taken the industry forward with a pilot-focused vision of flight
management. Today’s SBAS-capable FMSs build upon the company’s popular marketproven
product design, offering more advanced features and interfaces, and a growth
path to meet the requirements of the future.

Universal Avionics’ SBAS-capable FMS features
an extremely precise, internal SBAS Global
Positioning System (GPS) receiver that improves
accuracy and integrity of GPS-derived position
information. The Receiver Autonomous Integrity
Monitor (RAIM) prediction requirements in US
airspace are thereby removed and navigation
capabilities for all classes of aircraft in all phases
of flight are increased.

The embedded SBAS GPS receiver provides
ILS-like guidance down to near CAT I ILS
minimums.

Universal Avionics’ SBAS-FMS is compatible
with the regional SBAS around the world:

Europe – European Geostationary
Navigation Overlay Service (EGNOS)

North America – Wide Area
Augmentation System (WAAS)

Japan – Multi-functional Satellite
Augmentation System (MSAS)

India – GPS-Aided Geo-Augmented
Navigation (GAGAN)

FMS Flight Planning

The Flight Planning (FPL)
function provides you with the
quickest, most efficient means
of creating a flight plan, and
the most pilot-friendly method
of altering the flight plan elements as desired
or required by ATC. It has been engineered to
incorporate the greatest level of safety, with
numerous built-in safeguards such as the entry
of list-referenced selections which reduce both
keystrokes and errors.

The UNS-1Ew and UNS-1Fw
SBAS-FMSs provide a
Performance (PERF) option
for select aircraft types for
which performance charts
from the Airplane Flight Manual (AFM) are
digitized and stored in memory. These FMSs
will use pertinent data such as GW, ALT, OAT,
etc., to provide exact values for V1, VR and V2,
along with Takeoff N1.

Fuel Management

Using inputs from the fuel
flow sensors, the SBAS-FMS
provides real-time fuel
management with the most
extensive fuel information
and calculations available – the kind that can
eliminate unnecessary fuel stops, save you time
and money and provide increased safety. Specific range and endurance are provided
along with fuel, time and distance predictions
for your destination.

Lists

The unique LIST function
provides a quick and efficient
means to access and enter
data, minimizing alphanumeric
entries and reducing
input errors. The “smart” lists are geographically
prioritized based on aircraft position and course,
then alphabetized on each page. You can
quickly enter airports, navaids, intersections
and airways all by simply entering the list
reference number corresponding to the data
desired.

The SBAS-FMS will fly all
procedural leg types in accordance
with ARINC 424. This
sophisticated capability allows
you to fly the most complex
procedures such as heading to altitude, precision
arc, procedure turn, holding pattern and
more – all the necessary maneuvers required
to accurately fly SIDs, STARs and approaches.

Direct-To

The Direct-To (DTO) function
key is specifically dedicated
for flight plan changes in
response to “Direct-To” clearances.
The SBAS-FMS easily
takes you from your present position direct to
any point on or off your flight plan using circular
arc steering. If the desired waypoint is on the
flight plan, it may be selected by entering its
list reference number. If the desired waypoint is
not on the flight plan, the LIST function can be
used to access other waypoints/airports within
the surrounding area from the database, or the
identifier can be manually entered into the field.

Vertical Navigation

Universal Avionics’ SBAS-FMSs
incorporate the most advanced
concepts in vertical guidance
and control. VNAV pages
provide for such features as
computed Top-Of-Descent, Target Vertical
Speed indication and selection, and Vertical
Direct-To commands. Vertical waypoints can
be conveniently defined with altitudes or
Flight Levels, and lateral offsets.

Frequency Management

Frequency management
capabilities allow you to
tune your NAV and COMM
radios through the SBASFMS
– completely interfaced
with your existing Radio Management Unit.
The SBAS-FMS presents a list of suggested
COMM, Nav and NDB frequencies pre-selected
based on aircraft position and phase of flight.
Additionally, you can customize the radios
tuned through the SBAS-FMS by storing an
“active” and up to four “preselect” frequencies.
A “recall” feature allows you to swap the active
with the last frequency tuned without affecting
the preselect frequencies.

Messages

An extensive library of messages
has been programmed into
the SBAS-FMS. The message
annunciator alerts you of system
status advisories, including way-
point alerts, sensor watchdog functions, TAWS
alerts and self-test. “Pop-up” messages in response to invalid entries
further simplify system operation. The Message
(MSG) key may also be used to access datalink
communications should this optional equipment
be installed.

Holding Patterns

Holding patterns are accurately flown through
the SBAS-FMS automatically, complete with
appropriate entry procedure: direct, parallel
or teardrop. The navigation database includes
holding patterns that are part of departure,
arrival, approach and missed approach procedures.
The aircraft will fly the normal flight plan
legs and then automatically enter the holding
pattern upon reaching the holding fix. You
may also manually define a holding pattern by
specifying the holding fix, inbound course, turn
direction and either time or distance of holding
leg. When armed, the holding pattern will be
entered automatically upon reaching the fix.
A DTO HOLD command is also provided to
enable you to go direct to a holding fix at any
time.

Approach

Once near your destination, you can easily link
the appropriate approach for the active runway
into your flight plan. Approaches and runways
from the navigation database, and those which
have been pilot defined, are easily accessed.

Display and User Control

Display and user control is provided through the
4-inch or 5-inch FPCDU. A Multi-functional
Control Display Unit (MCDU) is specially tailored
for airline or special mission operations. Universal’s
FPCDUs feature graphics capabilities and incorporate
the latest technology in Active Matrix
Liquid Crystal color Displays (AMLCD). They
feature the highest contrast, lowest reflection
and greatest horizontal and vertical viewing
angles available, and offer superb sunlight
readability. Unique parallax control is also
provided. The system uses two character sizes
and line graphics to enhance data recognition.

Night Vision Goggle-Compatible

Universal Avionics’ 4-inch and 5-inch FPCDUs
are modified with Night Vision Goggle (NVG)-
compatible glass display panels, which changes
the lighting output in such a way that the unit
can be used in flight decks where operators are
wearing night vision goggles.
